MEANS FOR AUTGMATICALLY INDIGATING 'rnn arenoxima'rn NUMBER on wasps AND OTHER CHARACTERS WRITTEN n r TYPE-,WRITING MACHINES.

To all whom it may .concarn;

Be it; known that we, Riormnn Josarn. SHARP, of 16 Preston Park avenue, Brighton, county of Sussex, solicitor, and Man- COLM QUnnci-I, of 3:4. Sydney street, Brighton,

also of Sussex, England, solicitor-s clerk, have invented new and useful Improvements in Means for Approximate lllnnher of lVords and other Characters 'l'i ritten by Type-"Writing Mawords written upon such machines; and in sists ofa set of wheels in train one w) carrying thesaine into cilfect we make use of ya counting mechanism which we adapt in suitable manner for the purpose, as hereinafter described, and attach to or connect with the type writing machine-so (that snc i mechai'iisin maybe operated by the ments oil the spacing bar of the type w. machine.

The counting mechanism aforesaid condie other, and which wheels are tooth their peripheries and are each formed a horizontally, projecting flange. Upon. the flange of one wheel are inscribed numerals which indicate the number of words or other characters written, and which numerals are brought consecutively, (as the words or the like are written and the wheel is rotated by the operations of the spacing bar) beneath a sighting space formed in a. casing or cover with which the mechanism may be provided, or they may be otherwise brought separately, and distinctively to View. I This wheel is formed with a number of teeth on its periph crycorrespoiaiing to the number required. to complete a given measure of words as, say, 7 2 tcetlnwhen. it is desired to count the noun her ofiwords or the in folios of 72 as used by lawyers) so that in such instance one complete revolution of the wheel'indicates a folio of 752 words iand when such revolution is coinplct'eda second wheel is actuated upon a horizontally extending flange on which are inscribed numerals which indicate the 1111111 ber of ,folios Written. This second wheel is operated at 7 Specification of Letters Patent. Application filed September 9,18%;

every complete revolution of the first wheel i aforesaid. Further wheels may be made use of, to be operated by the second Wheel, or others provided, so that practically an unlimited numbcr of words, separately or of folios, or other measures of words, and words collectively may be registered, if desired,

The mechanism above mentioned is operated by inc-ans 0t alever pivoted at one end wi the casing of the mechanism, or in any vpavement position, carrying a pawl r w e latter or agitated by the operator a the cl word or the like. spacing bar depresses the pivoted lever and withdraws the pawl from the wheel but upon the release of the spacing bar the upward movement of, the pivoted lever, conse- (iii-U251 upon the action of the spring proi ided, as aforesaid, reengages the pawl with the teeth of the wheel and causes it to rotate to the extent of one tooth and register the completion of one word or the like. The

ii lie depression oi" the" pawl ahove mentionedis pivotedto its supporting lever and isv controlled by a. spring which when the pawl is disengaged from the pawl down to the e 'tent one tooth oi'the wheel so that as gagen'icnt. is made the pawl takes aga inst the next lower tooth to the one previously engaged with and as it rises to the full extent of the upward movement of the pivoted lever causes the wheel to turn to the extent of that one tooth. seen that the counting mechanism records the number of movements of the space bar. The casing or frame of the above described counting mechanism may be mounted in suit 31c guides or .1 1 formed in a conv'ei'iient position for in purpose upon the type writing machine or its stand in such manner tha it may be drawn out of action wl' en rcquiii l.

Mechanism such as hereinafter described or of other suitable character may be provided for resetting the counting mechanism when required.

the accom 'lanying drawings Figure 1 representing shows the counting mechanism above described attached to the frame of a type writing machine. Fig. 2 shows it as attached to the stand of the machine. Fig. 3,

to an enlarged scale, shows the lever actuating the counting mechanism and the means employed for adjusting such lever to the various heights of the spacing bar to adapt the mechanism to different machines. Fig. 4: is a front elevational view of the counting mechanism with the cover removed and Fig. 5 is a plan of the same with the top removed. Fig. 6 is a fragmentary sectional view, partly in elevation, showing the manner of shifting the second wheel one step upon completion of each revolution of the first wheel. Fig. 7 shows a detail of wheel, 6.

a represents the casing in which the counting mechanism is inclosed.

b is the first wheel above mentioned and which is formed with 72 or other given number of teeth upon its periphery and with a horizontal flange 0 imprinted with numerals up to 72 or other given number to indicate the number of words or other characters one folio or other measure of words or the like; d are sighting spaces see Figs. 1 and 2) in the casing a to enable the numerals to be read. This wheel I) indicates the number of words or the like written up to one :tolio or other measure.

a is the second wheel operated by the spur f on the wheel I) in such manner that one complete revolution of the wheel 7) moves the wheel 6 one tooth. The flange g on this wheel 9 is imprinted with numerals which indicate the number of folios or other measure of words or the like written.

his the mechanism operating lever pivoted within the casing at i and which is extended beyond the casing a as shown, so as to be depressed at its outer end by the spacing bar when the latter is pressed downward by the operator at the end of a word or other character.

Z is the spring controlling the movement of the lever h as aforesaid.

m is the pawl pivoted which engages with the teeth of the wheel I) and rotates the said wheel as and when the spacing bar 7.: is operated.

n is the spring connected at one end to the pawl m and at its other to the lever h and 0, 0, indicate pawls provided which on gage with the toothed wheels aforesaid to prevent any the same.

Though in the drawings only two numeral wheels are shown'it will be understood that any number of such wheels may be made use of so engaging one with the other that any number of characters or folios may be registered separately or collectively without the instrument requiring re-setting.

backward movement of to the lever h and Suitable mechanism may be provided for the purpose of 're-setting the counting wheels and releasing the same from the pawls to enable them to be brought to the starting position when required. Such a mechanism consists of a cog wheel or pinion p fixed upon a hollow spindle g passing through the front of the casing a and terminating in a milled head 7* outside the casing. The hollow spindle q fits upon a rod or pin a fixed to the back of the casingaand is capable of sliding upon the end thereof, aspring t surrounds the pin 8 and is interposed be tween the back of the casing and the cog p, aforesaid and tends to keep the cog out of gear with the toothed counting wheel. \Vhen, however, it is required to reset the mechanism to its starting position the head 1" is pressed inwardly until the cog p engages with its toothed counting wheel and the said milled head 1' is then turned until the counting wheel is in its required position. Then upon being released the cog is thrown out of gear by means of the spring 1 aforesaid. The mechanism in its casing as above described is attached to the frame or stand of the type writing machine in a position suitable for the operations of the spacing bar to actuate the counting wheels by means of the pivoted lever and its pawl in the manner above described, and is mounted in runners or guides u so that the same may be brought in and out of action as required; while to adjust the device to the varying heights of the spacing bars in different machines the pivoted lever h aforesaid (see particularly Fig. 1) is fitted at its end with a screwed pin '0 with which spacing bar 70 and which may be adjusted to suit requirements, or, as shown in Figs. 2 and 3 the lever It may terminate in a vertical screwed portion 71. upon which the contact arm or member to is supported on the spring 00 and the heightor level of such arm w may be regulated by means of the nut y screwed upon the end it of the lever h.
